question 27

Multiple Choice

A grower claims that only 13% of the strawberries he grows are unsatisfactory.When a truckload of his strawberries arrives at a farmers' market,one basket containing approximately 105 strawberries is examined for bruised or rotten fruit.Are the conditions satisfied for use of the Normal model?

• A)The 10% condition is satisfied since the strawberries are a random sample,are independent of each other,and likely represent less than 10% of all the grower's strawberries.The success/failure condition is not satisfied since only one basket is being examined.
• B)The conditions are satisfied since the population distribution is Normal.
• C)Since the strawberries are in the same basket,they may not be independent of each other,or be a random sample.Growing or storage conditions could affect all the strawberries in a basket.The success/failure condition is not satisfied since only one basket is being examined.
• D)The 10% condition is satisfied since the strawberries are a random sample,are independent of each other,and likely represent less than 10% of all the grower's strawberries.The success/failure condition is satisfied since np = 13.65 ≥ 10 and nq = 91.35 ≥ 10.
• E)Since the strawberries are in the same basket,they may not be independent of each other,or be a random sample.Growing or storage conditions could affect all the strawberries in a basket.The success/failure condition is satisfied since np = 13.65 ≥ 10 and nq = 91.35 ≥ 10.
